Rapid Manufacturing of Metal Components by Laser Forming
TL;DR: In this article, the main driving force of rapid prototyping or layer manufacturing techniques changed from fabrication of prototypes to rapid tooling (RT) and rapid manufacturing (RM), and nowadays, the direct fabrication of functional or structural end-use products made by layer manufacturing methods, i.e. RM, is the main trend.
